Believers need to ask the Lord to help us keep a humble spirit and an open mind so that He can teach us His truth. Far too often we base what we believe on what we've been taught, or on tradition, and not on the clear Word of God.
Ephesians 1:17 That the God of our Lord Jesus Christ, the Father of glory, may give unto you the spirit of wisdom and revelation in the knowledge of him:
[18] The eyes of your understanding being enlightened; that ye may know what is the hope of his calling, and what the riches of the glory of his inheritance in the saints.
[19] And what is the exceeding greatness of his power to us-ward who believe, according to the working of his mighty power,
When our hearts and minds are controlled by the Word of God under the direction of the Spirit of God, He enables us to understand the deep things of God and how they relate to everyday life. When that happens, the Bible and the truths it contains become intensely practical in our daily lives. It is so important that we study “all” the Bible.
